Japanese knotweed (Fallopia japonica) is the most commonly surveyed invasive plant in the UK. It is a Schedule 9 species under the Wildlife and Countryside Act 1981 and classified as controlled waste when removed from land under the Environmental Protection Act 1990.
The implications of Japanese knotweed for property owners, buyers, sellers and developers are significant. Its presence is required to be disclosed in property transactions and can affect mortgage availability. On development sites, it can affect planning conditions, construction programmes and funding arrangements.

Why management matters
Japanese knotweed does not go away without active management. Untreated infestations grow larger each year. Early, professional management is significantly less expensive and complex than dealing with an established, widespread infestation later.
